Definitions

  • This application relates generally to methods and apparatus for controlling fluid flow in a wellbore, and more particularly to an improved inflow control device (ICD).
  • ICD inflow control device
  • ICDs Inflow Control Devices
  • Inflow Control Devices are designed to improve completion performance and efficiency by balancing inflow throughout the length of a completion. Differences in influx from the reservoir can result in premature water/gas breakthrough, leaving valuable resources in the ground. Typical applications include wells experiencing "heel-toe” effects, breakthrough of water/gas, permeability differences, and water challenges in high viscous oil reservoirs. Another benefit of this technology is that it can balance the fluid injected into the formation in injection wells.
  • U.S. Pat. Nos. 7,469,743 and 7,802,621 the entire disclosures of which are incorporated herein by reference for all purposes, disclose ICDs for sand control screens.
  • An example of an inflow control device is commercially available from Halliburton Energy Services, Inc. under the trade mark EquiFlow® Inflow Control Device.
  • the EquiFlow® ICD consists of an annular chamber on a standard oilfield tubular. If screen is required, the reservoir fluid is produced from the formation, through the sand screen and into the flow chamber. The flow continues through a set of tubes, which creates a pressure drop, and then into the pipe through a set of ports. Tube length and ID are designed to give the pressure drop needed for optimum completion efficiency.
  • EquiFlow® Adjustable ICDs are pre- configured with a set of tubes that may be re-configured on the rig to change the pressure drop. A slidable housing provides flow tube access. Typically, multiple tubes per ICD are used. Disclosure regarding the EquiFlow® ICD is available on-line.
  • ICD In many applications, it is beneficial to run the ICD in a closed position during installation. This allows for circulation of fluid down to the shoe and up the annular space outside of a sand screen without using a wash pipe. It is also possible to pressurize the completion to activate other components, like open hole packers.
  • a delayed opening valve has been developed as well. This valve is activated by applying a high tubing pressure to shear a mechanism. Halliburton Energy Services, Inc. manufactures and markets a remotely-opened valve for use with ICDs which holds internal pressure when closed, but opens the screen to full production flow after sufficient internal pressure is applied and released.
  • a remote-open valve is typically installed on each joint of screen, with the valves in the closed position as the screens are run into the well.
  • valves are sealed to internal pressure only, allowing the screens to fill with well fluid when they are run into the well.
  • the entire completion assembly including the screens can be pressurized internally to pressure test the tubing, and pressure can be applied to set downhole devices, such as packer or other operational tools in the completion string.
  • the valve mechanism is made up of a collet and ball assembly with the collet held in a run-in position by an externally inserted shear pin. When enough pressure is applied, the shear pin shears, the collet shifts and locks in an open position while still holding tubing pressure.
  • the number of remote-open valve units is determined by the flow rate required or desired.
  • U.S. Pat. No. 7,762,341 discloses a flow control device utilizing a reactive media, comprising a flow path associated with a production control device (e.g., sand screen and ICD); an "occlusion member” (e.g., piston) positioned along the flow path that moves between an open position and a closed position, the occlusion member being activated by a change in a pressure differential in the flow path; and a "reactive media” (e.g., a water swellable material or an oil swellable material) disposed along the flow path that changes a pressure differential across at least a portion of the flow path by interacting with a selected fluid (e.g., water, of a sufficient concentration or amount, encountered by the production control device) to thereby actuate the occlusion member.

  • fluid flow is regulated between a wellbore and a tubular by moving a flow regulator device, such as an elongated tube, restrictor, etc., from a closed position to an open position wherein fluid flows through the flow regulator device in response to swelling of a swellable actuator.
  • the swellable actuator is positioned adjacent the flow regulator and moves the regulator between positions upon swelling.

Abstract

L'invention porte sur un ensemble de commande d'écoulement pour réguler un écoulement de fluide dans un puits de forage. Un dispositif de commande d'écoulement d'entrée à ouverture à distance est ouvert en réponse au gonflement d'un actionneur gonflable. L'actionneur gonflable peut déplacer un régulateur d'écoulement radialement, de façon périphérique, etc., de telle sorte qu'un écoulement est admis à travers le régulateur. En variante, l'actionneur gonflable peut déplacer un ou plusieurs éléments de vanne jusqu'à une position ouverte, de façon à permettre ainsi à un fluide de s'écouler à travers la vanne et jusqu'au régulateur d'écoulement. L'actionneur gonflable peut être gonflé en réponse à l'introduction de produits chimiques ou de chaleur. Un mécanisme de guidage peut être utilisé pour commander le gonflement de l'actionneur ou le mouvement du dispositif de régulateur ou de l'élément de vanne.
